The signal processing of the Norwegian Multistatic Radar DiMuRa has been presented. The radar uses binary phase coding with a class of binary phase codes with optimal autocorrelation properties. These codes are used to find the range to the target through a correlation process. These codes cannot be used to directly extract the target's velocity. This can, however, be accomplished through a Fourier transform of all the range correlation vectors for each range distance. Results from signal simulation and from a radar trial have been presented in detail.
